AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: The FAA is superseding an existing airworthiness directive 
(AD) that applies to all of the McDonnell Douglas Corporation airplanes 
identified above. The existing AD currently requires revising the 
maintenance program to incorporate new airworthiness limitations for 
fuel tank systems to satisfy Special Federal Aviation Regulation No. 88 
requirements. This new AD adds requirements to revise the maintenance 
program to incorporate specific Critical Design Configuration Control 
Limitations (CDCCL) information and install fuel tank float switch in-
line fuses. This new AD also adds two Airworthiness Limitations 
inspections (ALIs). This AD results from a design review of the fuel 
tank systems. We are issuing this AD to prevent the potential for 
ignition sources inside fuel tanks caused by latent failures, 
alterations, repairs, or maintenance actions, which, in combination 
with flammable fuel vapors, could result in a fuel tank explosion and 
consequent loss of the airplane.

DATES: This AD becomes effective November 12, 2010.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in the AD as of November 12, 
2010.
    On May 27, 2008 (73 FR 21523, April 22, 2008), the Director of the 
Federal Register approved the incorporation by reference of a certain 
other publication listed in the AD.

SUPPLEMENTARY INFORMATION: 

Discussion

    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 
CFR part 39 to include an AD that supersedes AD 2008-09-04, Amendment 
39-15484 (73 FR 21523, April 22, 2008). The existing AD applies to all 
Model DC-8-31, DC-8-32, DC-8-33, DC-8-41, DC-8-42, and DC-8-43 
airplanes; Model DC-8-50 series airplanes; Model DC-8F-54 and DC-8F-55 
airplanes; Model DC-8-60 series airplanes; Model DC-8-60F series 
airplanes; Model DC-8-70 series airplanes; and Model DC-8-70F series 
airplanes. That NPRM was published in the Federal Register on June 25, 
2010 (75 FR 36298). That NPRM proposed to continue to require revising 
the maintenance program. That NPRM also proposed to add requirements to 
revise the maintenance program to incorporate specific Critical Design 
Configuration Control Limitations (CDCCL) information and install fuel 
tank float switch in-line fuses. That NPRM also proposed to add two 
Airworthiness Limitations inspections (ALIs).

Relevant Service Information

    We reviewed Boeing DC-8 Special Compliance Item Report, MDC-
02K9030, Revision D, dated June 9, 2010. This service information does 
not add any additional work. We have revised paragraphs (j), (m), and 
(n) of this AD to refer to this report.

Comments

    We provided the public the opportunity to participate in the 
development of this AD. No comments have been received on the NPRM or 
on the determination of the cost to the public.

Change to Paragraph Reference

    We revised paragraph (l) of this AD to correct a typographical 
error that appeared in the NPRM. In paragraph (l) of the NPRM, we 
inadvertently referred to ``paragraph (k)'' instead of ``paragraph 
(j)'' of the AD. Paragraph (l) of this final rule correctly references 
paragraph (j) of this AD.

Explanation of Additional Change to NPRM

    We also clarified the airplanes affected by paragraph (k) of this 
AD by referring to the airplanes identified in Boeing Service Bulletin 
DC8-28-090, dated October 9, 2009. Airplanes not listed in the 
effectivity of Boeing Service Bulletin DC8-28-090, dated October 9, 
2009, are not required to do the installation required by paragraph (k) 
of this AD.

Conclusion

    We have carefully reviewed the available data and determined that 
air safety and the public interest require adopting the AD with the 
changes mentioned previously.

Costs of Compliance

    There are about 125 airplanes of the affected design in the 
worldwide fleet. The following table provides the estimated costs for 
U.S. operators to comply with this AD.

                                                                     Estimated Costs

Authority for This Rulemaking

    Title 49 of the United States Code specifies the FAA's authority to 
issue rules on aviation safety. Subtitle I, section 106, describes the 
authority of the FAA Administrator. Subtitle VII, Aviation Programs, 
describes in more detail the scope of the Agency's authority.
    We are issuing this rulemaking under the authority described in 
subtitle VII, part A, subpart III, section 44701, ``General 
requirements.'' Under that section, Congress charges the FAA with 
promoting safe flight of civil aircraft in air commerce by prescribing 
regulations for practices, methods, and procedures the Administrator 
finds necessary for safety in air commerce. This regulation is within 
the scope of that authority because it addresses an unsafe condition 
that is likely to exist or develop on products identified in this 
rulemaking action.

Regulatory Findings

    We have determined that this AD will not have federalism 
implications under Executive Order 13132. This AD will not have a 
substantial direct effect on the States, on the relationship between 
the national government and the States, or on the distribution of power 
and responsibilities among the various levels of government.
    For the reasons discussed above, I certify that this AD:
    (1) Is not a ``significant regulatory action'' under Executive 
Order 12866;
    (2) Is not a ``significant rule'' under DOT Regulatory Policies and 
Procedures (44 FR 11034, February 26, 1979); and
    (3) Will not have a significant economic impact, positive or 
negative, on a substantial number of small entities under the criteria 
of the Regulatory Flexibility Act.
    We prepared a regulatory evaluation of the estimated costs to 
comply with this AD and placed it in the AD docket. See the ADDRESSES 
section for a location to examine the regulatory evaluation.
